Advertising And Collusion In Retail Markets, Kyle Bagwell, Gea Myoung Lee
Advertising And Collusion In Retail Markets, Kyle Bagwell, Gea Myoung Lee
Research Collection School Of Economics
We consider non-price advertising by retail firms that are privately informed as to their respective production costs. We first analyze a static model. We construct an advertising equilibrium, in which informed consumers use an advertising search rule whereby they buy from the highest-advertising firm. Consumers are rational in using the advertising search rule, since the lowest-cost firm advertises the most and also selects the lowest price. Even though the advertising equilibrium facilitates productive efficiency, we establish conditions under which firms enjoy higher expected profit when advertising is banned. Consumer welfare falls in this case, however. We next analyze a dynamic …
Target Saving In An Overlapping Generations Model, Brishti Guha, Ashok S. Guha
Target Saving In An Overlapping Generations Model, Brishti Guha, Ashok S. Guha
Research Collection School Of Economics
We examine a model in which the utility function has been engineered so that it is optimal for consumers to aim for a fixed target level of retirement resources. In this case, consumption displays excess sensitivity to current income as well as perfect old age insurance. In an overlapping generations model, this leads naturally to multiple and unstable equilibria. Under static expectations, it also leads to a well-defined dynamics, including possible historical traps, implosions involving ever-diminishing capital stock and ever-increasing interest rates, and the feasibility of optimal one-time interventions.
Financial Frictions, Capital Reallocation, And Aggregate Fluctuations, Jürgen Von Hagen, Haiping Zhang
Financial Frictions, Capital Reallocation, And Aggregate Fluctuations, Jürgen Von Hagen, Haiping Zhang
Research Collection School Of Economics
We address an important business cycle fact, i.e., the amplified and hump-shaped responses of output to productivity shocks, in a dynamic general equilibrium model with financial frictions. Models with financial frictions in the current literature have either the amplification mechanism or the propagation mechanism. Our model shows that the dynamic interaction of borrowing constraints, endogenous capital accumulation, and capital reallocation among agents with different productivity constitutes a mechanism through which the effects of productivity shock on aggregate output are amplified and propagated, more in line with the empirical evidence than other related models in the literature.
Testing Intergroup Concordance In Ranking Experiments With Two Groups Of Judges, Dawn J. Dekle, Leung, Denis H. Y., Min Zhu
Testing Intergroup Concordance In Ranking Experiments With Two Groups Of Judges, Dawn J. Dekle, Leung, Denis H. Y., Min Zhu
Research Collection School Of Economics
Across many areas of psychology, concordance is commonly used to measure the (intragroup) agreement in ranking a number of items by a group of judges. Sometimes, however, the judges come from multiple groups, and in those situations, the interest is to measure the concordance between groups, under the assumption that there is some within-group concordance. In this investigation, existing methods are compared under a variety of scenarios. Permutation theory is used to calculate the error rates and the power of the methods. Missing data situations are also studied. The results indicate that the performance of the methods depend on (a) …
Optimal Collusion With Internal Contracting, Gea Myoung Lee
Optimal Collusion With Internal Contracting, Gea Myoung Lee
Research Collection School Of Economics
In this paper, we develop a model of collusion in which two firms play an infinitelyrepeated Bertrand game when each firm has a privately-informed agent. The colluding firms, fixing prices, allocate market shares based on the agent’s information as to cost types. We emphasize that the presence of privately-informed agents may provide firms with a strategic opportunity to exploit an interaction between internal contracting and market-sharing arrangement: the contracts with agents may be used to induce firms’ truthful communication in their collusion, and collusive market-share allocation may act to reduce the agents’ information rents.
Mapping The Discipline Of The Olympic Games An Author-Cocitation Analysis, Peter Warning, Rosie Ching, Kristine Toohey
Mapping The Discipline Of The Olympic Games An Author-Cocitation Analysis, Peter Warning, Rosie Ching, Kristine Toohey
Research Collection School Of Economics
The authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the …
Optimal Bandwidth Selection In Heteroskedasticity-Autocorrelation Robust Testing, Yixiao Sun, Peter C. B. Phillips, Sainan Jin
Optimal Bandwidth Selection In Heteroskedasticity-Autocorrelation Robust Testing, Yixiao Sun, Peter C. B. Phillips, Sainan Jin
Research Collection School Of Economics
This paper considers studentized tests in time series regressions with nonparametrically autocorrelated errors. The studentization is based on robust standard errors with truncation lag M = bT for some constant b ∈ (0, 1] and sample size T. It is shown that the nonstandard fixed-b limit distributions of such nonparametrically studentized tests provide more accurate approximations to the finite sample distributions than the standard small-b limit distribution. We further show that, for typical economic time series, the optimal bandwidth that minimizes a weighted average of type I and type II errors is larger by an order of magnitude than the …
Refined Inference On Long Memory In Realized Volatility, Peter C. B. Phillips, Offer Lieberman
Refined Inference On Long Memory In Realized Volatility, Peter C. B. Phillips, Offer Lieberman
Research Collection School Of Economics
There is an emerging consensus in empirical finance that realized volatility series typically display long range dependence with a memory parameter around 0.4 (Andersen et al., 2001; Martens et al., 2004). The present article provides some illustrative analysis of how long memory may arise from the accumulative process underlying realized volatility. The article also uses results in Lieberman and Phillips (2004, 2005) to refine statistical inference about by higher order theory. Standard asymptotic theory has an error rate for error rejection probabilities, and the theory used here refines the approximation to an error rate of. The new formula is independent …
Two-Sample Estimation Of Poverty Rates For Disabled People: An Application To Tanzania, Tomoki Fujii
Two-Sample Estimation Of Poverty Rates For Disabled People: An Application To Tanzania, Tomoki Fujii
Research Collection School Of Economics
Estimating poverty measures for disabled people in developing countries is di cult, partly because relevant data are not available. We develop two methods to estimate poverty by the disability status of the household head. We extend the small-area estimation proposed by Elbers, Lanjouw and Lanjouw (2002, 2003) so that we can run a regression on head's disability status even when such information is unavailable in the survey. We do so by aggregation and by moment adjusted two sample instrumental variable estimation. Our results from Tanzania show that both methods work well, and that disability is indeed associated with poverty.

Education And Trade, Pao Li Chang, Fali Huang
Education And Trade, Pao Li Chang, Fali Huang
Research Collection School Of Economics
This paper examines the inherent link between a countryís education system and its comparative advantage in trade. It suggests that di§erences in education systems across countries are probably a stable equilibrium result that is compatible with and reinforced by trade patterns. In equilibrium, two distinct types of countries emerge, one that exports creativity-intensive products and has an education system encouraging diversity (as illustrated by the US), and the other one that exports high-quality manufactured products and has an education system promoting homogeneity in student quality (as illustrated by Japan). Our Öndings present a novel explanation for the coexistence of low …
Rational And Boundedly Rational Behavior In Sender-Receiver Games, Massimiliano Landi, Domenico Colucci
Rational And Boundedly Rational Behavior In Sender-Receiver Games, Massimiliano Landi, Domenico Colucci
Research Collection School Of Economics
The authors investigate the strategic rationale behind the message sent by Osama bin Laden on the eve of the 2004 U.S. Presidential elections. They model this situation as a signaling game in which a population of receivers takes a binary choice, the outcome is decided by majority rule, sender and receivers have conflicting interests, and there is uncertainty about both players’ degree of rationality. They characterize the structure of the sequential equilibria of the game as a function of the parameters governing the uncertainty and find that in all pure strategy equilibria, the outcome most preferred by the rational sender …
Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips
Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips
Research Collection School Of Economics
Stable autoregressive models are considered with martingale differences errors scaled by an unknown nonparametric time-varying function generating heterogeneity. An important special case involves structural change in the error variance, but in most practical cases the pattern of variance change over time is unknown and may involve shifts at unknown discrete points in time, continuous evolution or combinations of the two. This paper develops kernel-based estimators of the residual variances and associated adaptive least squares (ALS) estimators of the autoregressive coefficients. Simulations show that efficiency gains are achieved by the adaptive procedure.

Unit Root Model Selection, Peter C. B. Phillips
Unit Root Model Selection, Peter C. B. Phillips
Research Collection School Of Economics
Some limit properties for information based model selection criteria are given in the context of unit root evaluation and various assumptions about initial conditions. Allowing for a nonparametric short memory component, standard information criteria are shown to be weakly consistent for a unit root provided the penalty coefficient Cn?? and Cn/n?0 as n??. Strong consistency holds when Cn/(log logn)3?? under conventional assumptions on initial conditions and under a slightly stronger condition when initial conditions are infinitely distant in the unit root model. The limit distribution of the AIC criterion is obtained.
Nonstationary Discrete Choice: A Corrigendum And Addendum, Peter C. B. Phillips, Sainan Jin, Ling Hu
Nonstationary Discrete Choice: A Corrigendum And Addendum, Peter C. B. Phillips, Sainan Jin, Ling Hu
Research Collection School Of Economics
We correct the limit theory presented in an earlier paper by Hu and Phillips [2004a. Nonstationary discrete choice. Journal of Econometrics 120, 103-138] for nonstationary time series discrete choice models with multiple choices and thresholds. The new limit theory shows that, in contrast to the binary choice model with nonstationary regressors and a zero threshold where there are dual rates of convergence (n1/4 and n3/4), all parameters including the thresholds converge at the rate n3/4. The presence of nonzero thresholds therefore materially affects rates of convergence. Dual rates of convergence reappear when stationary variables are present in the system. Some …

Incidental Trends And The Power Of Panel Unit Root Tests, Hyungsik Roger Moon, Benoit Perrron, Peter C. B. Phillips
Research Collection School Of Economics
The asymptotic local power of various panel unit root tests is investigated. The (Gaussian) power envelope is obtained under homogeneous and heterogeneous alternatives. The envelope is compared with the asymptotic power functions for the pooled t-test, the Ploberger and Phillips [2002. Optimal testing for unit roots in panel data. Mimeo] test, and a point optimal test in neighborhoods of unity that are of order n-1/4T-1 and n-1/2T-1, depending on whether or not incidental trends are extracted from the panel data. In the latter case, when the alternative hypothesis is homogeneous across individuals, it is shown that the point optimal test …
Building Social Trust: A Human Capital Approach, Fali Huang
Building Social Trust: A Human Capital Approach, Fali Huang
Research Collection School Of Economics
Much evidence suggests individuals differ in their predisposition to cooperate, which is essentially a component of human capital. This paper examines the role of individual cooperative tendencies and their interactions with institutions in generating social trust; it also endogenizes cooperative tendencies using a human-capital investment model. Multiple equilibria and inefficiencies exist due to positive externalities. An innovative finding is that, when institutions are more effective in punishing defecting behaviors, more people invest in cooperative tendencies and hence the endogenous social trust is higher, though the equilibrium cooperative tendencies are lower. This paper provides a plausible explanation for many empirical and …

A Consistent Characteristic Function-Based Test For Conditional Independence, Liangjun Su, Halbert White
A Consistent Characteristic Function-Based Test For Conditional Independence, Liangjun Su, Halbert White
Research Collection School Of Economics
Y is conditionally independent of Z given X if Pr{f(y|X,Z)=f(y|X)}=1 for all y on its support, where f(·|·) denotes the conditional density of Y given (X,Z) or X. This paper proposes a nonparametric test of conditional independence based on the notion that two conditional distributions are equal if and only if the corresponding conditional characteristic functions are equal. We extend the test of Su and White (2005. A Hellinger-metric nonparametric test for conditional independence. Discussion Paper, Department of Economics, UCSD) in two directions: (1) our test is less sensitive to the choice of bandwidth sequences; (2) our test has power …
Singapore's Exchange Rate Policy: Some Implementation Issues, Hwee Kwan Chow
Singapore's Exchange Rate Policy: Some Implementation Issues, Hwee Kwan Chow
Research Collection School Of Economics
Reflecting the small open nature of its economy, Singapore has adopted an exchange rate-centered monetary policy framework since 1981. The exchange rate regime in Singapore is an intermediate regime that follows the basket-band-crawl system. With this managed float system, the MAS has successfully deterred speculators from attacking the domestic currency for most of the past three decades. At the same time, the flexibility accorded by the managed float system aided Singapore in escaping from the 1997–1998 Asian crisis relatively unscathed. In order to advance our understanding of the hitherto successful operation of Singapore's exchange rate policy, we examine the following …
Long Run Covariance Matrices For Fractionally Integrated Processes, Peter C. B. Phillips, Sik Kim Chang
Long Run Covariance Matrices For Fractionally Integrated Processes, Peter C. B. Phillips, Sik Kim Chang
Research Collection School Of Economics
An asymptotic expansion is given for the autocovariance matrix of a vector of stationary long-memory processes with memory parameters d ∈ [0,½). The theory is then applied to deliver formulas for the long-run covariance matrices of multivariate time series with long memory.Phillips acknowledges partial support from a Kelly Fellowship and from the NSF under grant SES 04-142254. This may be proved directly using a Fourier integral asymptotic expansion when the spectrum of the short-memory component is analytic.
Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii
Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii
Research Collection School Of Economics
The small-area estimation developed by Elbers, Lanjouw and Lanjouw (2002, 2003), in which a census and a survey are combined to produce the estimates of welfare measures for small geographic areas, has become a standard tool for poverty analysis in developing countries. The small-area estimates are typically plotted on a map, which are commonly called a poverty map. Poverty maps proved useful for policy analysis and formulation, and have become increasingly popular among policy-makers and researchers. In Cambodia, poverty maps have been used by various international organizations, ministries and non-governmental organizations for analyzing the poverty situations for their operation areas, …
Global Analysis Of An Expectations Augmented Evolutionary Dynamics, Angelo Antoci, Antonio Gay, Massimiliano Landi, Pier Luigi Sacco
Global Analysis Of An Expectations Augmented Evolutionary Dynamics, Angelo Antoci, Antonio Gay, Massimiliano Landi, Pier Luigi Sacco
Research Collection School Of Economics
We consider a deterministic evolutionary model where players form expectations about future play. Players are not fully rational and have expectations that change over time in response to current payoffs and feedback from the past. We provide a complete characterization of the qualitative dynamics so induced for a two strategies population game, and relate our findings to standard evolutionary dynamics and equilibrium selection when agents have rational forward looking expectations.
Tournaments With Ex Post Heterogeneous Agents, Theofanis Tsoulouhas, Kosmas Marinakis
Tournaments With Ex Post Heterogeneous Agents, Theofanis Tsoulouhas, Kosmas Marinakis
Research Collection School Of Economics
This paper compares relative performance evaluation via tournaments to absolute performance evaluation via piece rates when agents are heterogeneous ex post, to make the point that agent heterogeneity compromises the insurance function of tournaments. In particular, we show that the more heterogeneous agents are the less insurance can be offered through tournaments and the less dominant tournaments are over piece rates. Thus, absolute performance piece rates should be preferred when agents are highly heterogeneous. However, even with heterogeneous agents, tournaments become more desirable when the number of agents or the uncertainty about the common shock increases sufficiently.
Direction-Of-Change Forecasts Based On Conditional Variance, Skewness And Kurtosis Dynamics: International Evidence, Peter F. Christoffersen, Francis X. Diebold, Roberto S. Mariano, Anthony S. Tay, Yiu Kuen Tse
Direction-Of-Change Forecasts Based On Conditional Variance, Skewness And Kurtosis Dynamics: International Evidence, Peter F. Christoffersen, Francis X. Diebold, Roberto S. Mariano, Anthony S. Tay, Yiu Kuen Tse
Research Collection School Of Economics
Recent theoretical work has revealed a direct connection between asset return volatility forecastability and asset return sign forecastability. This suggests that the pervasive volatility forecastability in equity returns could, via induced sign forecastability, be used to produce direction-of change forecasts useful for market timing. We attempt to do so in an international sample of developed equity markets, with some success, as assessed by formal probability forecast scoring rules such as the Brier score. An important ingredient is our conditioning not only on conditional mean and variance information, but also conditional skewness and kurtosis information, when forming direction-of-change forecasts.
Wage Inequality, Intergenerational Mobility, And Education In Singapore, Kong Weng Ho
Wage Inequality, Intergenerational Mobility, And Education In Singapore, Kong Weng Ho
Research Collection School Of Economics
Accompanying Singapore’s phenomenal economic growth over the past four decades has been a rapid increase in educational attainment over the years. In 1960, the mean years of schooling for residents aged 25 and over was 3.14 years; in 2006, it was 9.3 years. This dramatic increase in the supply of skilled labour in all sectors of the economy helped to power Singapore’s high growth rates over the past few decades of economic development, which also saw declining wage inequality and high upward intergenerational mobility in education. However, we need to ask if these trends will continue in the future and …
Financial Development And International Capital Flows, Jürgen Von Hagen, Haiping Zhang
Financial Development And International Capital Flows, Jürgen Von Hagen, Haiping Zhang
Research Collection School Of Economics
We develop a general equilibrium model with nancial frictions in which internal capital (equity capital) and external capital (bank loans) have di erent rates of return. Financial development raises the rate of return on external capital but has a non-monotonic e ect on the rate of return on internal capital. We then show in a two-country model that capital account liberalization leads to out ow of nancial capital from the country with less developed nancial system. However, the direction of foreign direct investment (FDI, henceforth) depends on the exact degrees of nancial development in the two countries as well as …
Inefficient Worker Turnover, Nicolas L. Jacquet
Inefficient Worker Turnover, Nicolas L. Jacquet
Research Collection School Of Economics
This paper considers the efficiency properties of risk-neutral workers’ mobility decisions in an equilibrium model with search frictions, but no search externalities, when the rent accruing to a match is split through bargaining. Matches are ex ante homogeneous and their true productivity is learnt after the match is formed. It is shown that the efficiency of worker turnover depends on contract enforceability, and that in the absence of complete enforceability the equilibrium fails to be efficient. This is because without complete enforceability firms cannot credibly offer workers contracts that will guarantee them the entire future of all potential future matches.
